SPECIFICATIQN forming part of Letters Patent No. 681,239, dated August 27, 1901.

l Application iiled May 4, 1901. Serial No. 58,785. (No model.)

To all `whom it may concern:` `Be it known that I, ANTON METZEL, a sub- Ject of the Emperor of Austria-Hungary, re-

siding at Wheatland, in the countyof `Rice "l vide an arched axle 1. t n t n "ings,the arched axle comprises the central i and State of Minnesota, have invented a new and useful Sulky-Cultivator, of which the fol-` lowing is a specification. t

Myinvention is an improved sulkyfcultit "vatorg and it consists inthe peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the drawings, yFigure 1 is a side eleva.-

3 tion of a sulky-cultivator constructed in accordance withiny invention, showing the vai I riouscultivator-frames disposed in different positions. Fig. 2 is a top plan view ofthe same. Fig. 3 is a vertical longitudinal sectional view of the same, taken on a plane indicated bythe line a o; of Fig. 2. Figs. l and 5 are detailtopplan views showing means by which eithera two or three horse team may be attached tothe cultivator. Fig. 6 is a detail elevation of one of the shifting-levers for shiftingthe outer cultivator-framcs laterally. Fig. 7 is a detail view of the central cultivatorrframe.

. In the embodiment of my invention I pro- As shown in the drawcloss-bar 2 and the standards 3, which depend from` and are secured to theends theret of. `Said standards have on their outer sides t t l at their lower ends spindles 4, onwhich are l f ends.

`mounted the supporting-wheels 5.

A pair of draft-bars 6 are attached to the lcentral porttion of the arched axle, project forwardly therefrom, and converge toward their front To the under sides of said draft-bars at a suitable distance in advance of the arched axle are secured a pair of cross-bars 7 8, the latter beingna slight distance in ad-` Vance of the' former. lA substantially W- `shaped bent rod 9 is attached to the draft- `bars G at a slight distance in advance Oof the arched axle, as at 10. The front lower portions of said bent rod 9 form horizontal transversely-disposed outer pivotal spindles 11 and a centralpivotalspindle 12. `Said central spindle 12 is connected to the cross-bar 8 by rods 13. Said end spindles 11 are coni `nected to the end portions of the cross-bar 8 by rods 1t.` A draft-link 15 has its upper end llexibly connected to the central portion of cross-bar 7, as at 16. The lower end thereof is connected to the center of the spindle 12, as at 17. Similar draft-links 18 have their upper ends connected to the crossbar 7, as at 19, and their lower ends connected to the end spindles 1l by hooks or similar devices 20. Each of said draft-links 18 is provided with a series of adjusting-openings 2l for the attachment thereto of a singletree 22.

In connection with the sulky I employ a pair of outer cultivator-frames 23 and a centralcultivating-frame24. Eachof theframes 23 comprises a pair of longitudinal bars 24, which are shaped as shown in Fig. 2 and have their front ends pivoted on one of the outer spindles 11 and connected together by a crossbar 25, the rear ends of said bars 24a being connected together, as at 2G, a foot or standard 27 for a suitable cultivating point or shovel 28 being secured between the rear ends of said bars. Said bars arealso adapted for ithe attachment thereto of other feet or standards, as at 29. The front ends of the bars 24Ca are provided with elongated slots 30, through which the spindles 11 extend. Thereby the rear portions of said cultivatorframes 23 are adapted to be shifted laterally toward and `from Yeach other. motion of the said frames on the said spindles 11. Preferably, and as here shown, each of the feet or standards is provided with a pivoted lower section and with a wooden breakpin 28, whereby when one of the cultivating points or shovels encounters an unyielding obstruction the wooden pin breaks `and the lower section, with the point or shovel, turns back, thus avoiding breakage. Imay also, as here shown, employ fenders 3l in connection with the cultivating shovels or points, attached by their feet or standards tothe bars 24a. The form of the frames 23 here shown adapts the same for the attachment thereto of either three or ve cultivating points or shovels, as maybe desired. Within the scope The slots 30 admit of this i of my invention the construction of the frames c 23 may be modified, and I do not limitmyself in this particular. It will be observed `by IOO rear ends of said frames operate directly in rear of said wheels.

Inverted-U-shaped yokes 32 are disposed astride of and over the wheels and have their lower ends provided with slots 33. The lower ends of said yokes bear against the bars 24a of the cultivator-frames 23 and are attached thereto by bolts 34, which operate in said slots 33. Thereby said yokes are adapted to play vertically on said frames 23. Springs on said yokes bear downward on said bars of said cultivator-fram es. Hand-levers 36 are fulcrumed on brackets 37, which are attached to the arched axle and are provided with racksectors 38. The front ends of said hand-le- Vers are pivotally connected to the yokes 32, as at 39. Said levers, as will be understood, serve to raise and lower said yokes, and hence to raise and lower said cultivator-frarnes 23, and said levers are provided with suitable spring-pressed locking-dogs 40, of the usual construction, which by engagement with the rack-sectors 38 lock said levers, and hence said cultivatorframes,in any desired position. Owing to the springs 35, which bear downward on the cultivator-frames 23, and the lost motion between said frames and the yokes 32, said cultivator-frames are adapted when in operation to move upwardly independently of said yokes to permit the cultivating points or shovels to pass over an obstruction, as a stone or a root, and thereby avoid breakage.

A seat 41 for the driver is supported by bars 42, that project rearwardly from the arched axle. A pair of shifting-levers 43, which are of the construction shown in Fig. 6 ofthe drawings, are pivotally mounted, as at 44, on spindles 45, that project rearwardly from brackets 46, which are secured to the rear side of the arched axle. The outer arms 47 of said shifting-levers are slotted, as at 48, the inner bars 24a of the cultivatorframes 23 beingdisposed and adapted to play 4vertically in said slots 48, and the inner arms 49 ot' said shifting-,levers are provided with supports 49a for thefeet ofthe driver. Thereby the driver is enabled to shift the rear ends of the outer cultivating-frames 23 at will toward and from each other to avoid an obstruction or to avoid destroying stands of plants which are out of line with the rows.

The central cultivator-frame comprises a central bar 50 and a pair of side bars 5l. A pair of draft-links 52 are bolted to opposite sides of the central bar 50, at the front end thereof, and are pivotally attached at their front ends tothe spindle 12. The bars 51 have their front ends pivotally attached, as at 53, to a clip 54, of suitable construction, which is secured at the front end of the central bar 50. The latter is of suitable length and is adapted at its rear end to carry a suitable cultivating point or shovel, and on the said central bar 50 is a clip 55, whichis adapted to be movable longitudinally thereon. Links 56 are pivotally attached at their rear ends to the said slidable clip 55 and have their front ends pivotally connected to the rear ends'of the bars 51. A hand-lever 57 is pivotally connected at its lower end to the bar 50 and is provided with a spring -pressed locking dog 58, of the usual construction, which in coaction with a rack-segment 59 locks the said lever at any desired adjustment. Said lever is connected by a link 60 to the slidable clip 55. Hence by means of the said lever said clip may be adj usted forward or rearward on the bar 50, and the side bars 51 may be thereby adjusted laterally toward and from the center bar 50. Each of the side bars 51 is preferably of substantially the same form as the bars 24a of the side or outer cultivator-frames 23 and is adapted for carrying one or more cultivating points or shovels.

A hand-lever 6l is fulcrumed to a bracket 62, which is secured on the center of the arched axle and is provided with a segmentrack 63. Said hand-lever has a spring-pressed locking-dog 64, of the usual construction, which by engagement with the said segmentrack locks said lever at any desired adjustment. connected to the front end of said hand-lever 61. The lower portion of said link has a slot 66, and said link is attached to the central bar 50 of the central cultivator-frame bya pivotbolt 67, which operates in said slot. Thereby lost motion is provided between said link and said central cultivator-frame, and while the latter is adapted to be raised or lowered by said link when the hand-lever is operated said cultivator-frame is adapted to rise independently of said link and lever. A spring 68 on said link bears downward on the central cultivator-frame and keeps the same depressed, with its cultivating points or shovels in operation in the soil. In the event that an obstruction is encountered the spring 68 enables the cultivator-framcs to ride over the same.

The machine is adapted to be drawn by a two-horse team or a three-horse team, at will. When only three cultivating points or shovels are carried by each of the cultivatorframes, as shown in the drawings, two horses are enabled to readily draw the cultivator. When two horses are thus used, I provide the sulky-frame with a tongue 69, which is formed by prolonging the draft-bars 6. In this event the singletrees are attached to the draft-links 18 only. When three horses are used, I provide the cultivator-.frarne with a pair of draftpoles 70, as shown in Fig. 5. In this event a singletree is attached not only to each of the draft-links 18, but also to the central draftlink 15. One horse is disposed between the poles 70 and one on the outer sides thereof. Suitable neck-yokes 71 may, as is shown in Figs. 4 and 5, be also used. I

Having thus described my invention, I claim- 1. In a sulky-cultivator, the combination of a sulky-frame, cultivator-frames ieXibly connected thereto, means to raise and lower said A link 65 has its upper end pivotally IOO ` nected thereto, means to raise and lower said cultivator-frames, and shifting -levers fnlcrumed to said sulky-frame, said shiftingdel vers having slots 48 engaged `by bars of said cultivator frames, whereby the latter are adapted to play vertically in said shifting-lejvers, substantially as described.
